Application November 6, 1946, Serial No. I708,110

This invention relates to a mechanical reamer for tobacco pipes.

The object of the invention is to provide a pipe reamer which gives amechanical reaming action in the bowl of the pipe, with a minimum ofmechanical parts and with simplicity ofmechanical structure, whileperforming its :intended function under the iniiuence of simple and easymanual operation.

Another and conjoint object is to provide a pipe reamer of thedesignated sort which comprises means for receiving ashes. dottle andcrust removed from the bowl of a pipe, and :which reamer assembly is asa Whole of pleasing appearance.

In the accompanying drawings illustrative of my invention:

Fig. I is a lplan view of a pipe reamer constituting a simple embodimentof my invention.

Fig. II is a vertical sectional view through the reamer taken in theplane of the section line II-II of Fig. I.

Fig. III is a plan view of a, modified form of the reamer.

Fig. IV is a vertical sectional view through the reamer taken in theplane of the section 'line IV-IV of Fig. III.

Figs. V, VI and VII are vertical sectional views of further modiiiedforms of the reamer.

In the accompanying drawings reference numeral I designates a relativelydeep dish, which serves as a mounting base for the mechanical elementsof the reamer and as 'a receiver for ashes and dottle from tobacco pipesin the bowls of which the reamer acts. Secured in the bottom of dish Ithere is an upright pos-t i2, which desrably is mounted centrally of thedish, as shown, and which houses a spindle 3. Convenient means formounting post 2 in dish I are shown as a nut 2a on a threaded extension2b of post 2 and bearing against a, washer 2c on the under surface ofthe dish. A horizontal tool-:carrying arm 4 is mounted .on spindle 3,being 'shown as secured thereto 'by means of a. cap 5 threaded at 6 tothe upper region of the spindle. 'Ihe iball 'I shown in Figs. I and IIas mounted on toolcarrying arm Il is purely ornamental.

The reaming tool 8 is of a form usual in pipe reamers, desirably havinga double cutting thread 8a. This reaming tool 8 is non-rotatably mountedon horizontal arm 44 in a. position substantially removed from thevertical pivot provided by spindle 2. This eccentric mounting is such asto cause reaming tool 8 to move through a circular path of substantialradius when carrying arm '4 is rotated.

17 Claims. (Cl. 131-232) In use of the reamer, the bowl .of a pipe isplaced in an inverted position on reaming tool 8 'so that the toolenters or tends to enter the cavity of -the Vbowl. The s-tem of thevpipe -being firmly held bythe user, he provides' a simple crank motionl'by movement vsof his own arm to produce rotation of the tool-carryinglarm. 4 by Contact of the pipe bowl with the tool. The pipe `being heldfirmly lthere is then a single complete relative revolution of thereaming tool and vthe pipe bzowl for each revolution of thetool-carrying arm. As this action-proceeds the reaming tool dislodgesdottle fromv the pipe bowl, and may scrape the crust surrounding thecavityin the bowl to limit the thickness of such crust. Particles ofdislodged `dot'tle and scraped' crust, together with anyashes which maybe in the pipe bowl,fa.ll into dish I. l Y

In order to make sure that such particles are not nung outwardly beyondthe dish in rapid rotational movement of the reaming tool, itisdesirable to provide collecting means surrounding the tool. Such meansvare shown yas a cup mounted on tool-carrying arm 4 around Ithelreamingtool. VThe cup has a peripheral wall 9. which serves as a guard againstthe'dispersion of refuse from the pipe bowl and a. bottom having thereinrelatively large openings I0 for the discharge of refuse from the pipeinto theunderlying dish. 'I'he grid II shown in Figs. I-and II of thedrawings is a desirable adjunct tothe reamer assemlbly because itprovides an ornamental screen preventing accidental contact with refusereceived in the dish from the pipe bowl which is Ibeing cleaned.

It will readily be understood that the reaming action .on the bowl of atobacco pipe 'performed by my reamer assembly is particularlyadvantageous both lfrom the operative and the structural viewpoint. Onone hand it gives the desired relative rotation-between. the pipe bowland the reaming tool without the 'awkward physical movement on the part.of the user which is required if the bowl of a tobacco Vpipe be rotatedon a stationary reaming tool. Onv Athe Vother hand, 4the simplestructure involved in the rotatalble mounting of thereaming tool avoidsthe tendency to early mechanical lfailure which may Ibe met if complexpower-transmitting elements be included in a device of this sort.

In the modified form of my pipe reamer shown in Figs. III and IV ofthedrawing-s the horizontal arm 4 of Figs. I and II is replaced byafshallow cup `or pan I2 which servesgcompletelyto cot-er, and hide:therinterlior oi'thefdishIS. y"llan users arm which reams out a pipebowl in the A form of the device Ishown in Figs. I and II serves toperform an identical func-tion in the modifica'- tion of Figs. III andIV. I

As in the simpler form of Figs. I and II, means to prevent thevscattering" of pipe refuse desirably are provided in the modi.

III and IV. Such means comcup II, which as shown ned reamer of Figs.prise a circular guard or is made integral with the bottom of pan I2,and which itself is bottomless to permit refuse from the pipe to fallinto the underlying dish I3; The reaming tool I6 is mounted in uprightposition within cup I1 `on a spider I8 which is welded to or otherwisesuitably supported by the bottom of the pan at the edge of the openingbounded by the peripheral wall of the cup.

I'he modied form of my pipe reamer shown in Fig. V of the drawings isthe same as that shown in Figs. I and II except that the openings II! inthe bottom of the cup are-omitted and hence the discharge of refuse fromthe pipe is retained in the cup. v

Thusreference numeral I8 designates a relatively deep dish, whioh servesas a mounting base for the mechanical elements of 'the reamer and alsoas a receptacle for pipes, pipel cleaners and the like. Secured inthebottom of the dSh I8 there is an upright post I9,wh.ich desirably ismounted centrally of the dish, as shown,v 'and which houses a spindle20. Convenient means for mounting post I9 in dish I 8 is shown as a nut2| on a threaded extension 22 of post I9 and bearing against a washer 23on thev under suriac'eof' the dish. A horizontal tool-carrying arm 24 ismounted on spindle 20,'-being-shown as secured theretby means of a'cap25 threaded at 26 to the upper region of the spindle. The ball 21 shownas mounted onthe tool-carrying arm 24 is purely ornamental. f

The reaming tool28 is non-rotatably mounted in uprightposition onkhorizontalv arm 24l in a position substantially removed fromthe verticalpivot provided by spindle so that thesameA simple crank motion of theusers arm which reams out a pipe bowl in the form of the devicepreviously described serves to perform an identical function in themodification of Fig. V.

As in the previously described vforms of the device, means to preventscatteringv of pipe refuse desirably are provided in the modied reamerof Fig. V. Such means comprise a circular guard or cup 29 mounted on thetool-carrying arm 24 around the reaming tool 28. The cup 29 is providedwith an imperforate bottom 30 and hence the cup also functions as areceptacle for ashes and dottle from the tobacco pipes in the bowls ofwhich the reamer acts. The spindle 20` is readily removable from thepost I9 and hence the cup 29 may be separated from thedish I8 andemptied when desired. If desired, a grid 3l may be provided inthe dishI8.

In the modied form of my pipe reamer` illustrated in Fig. VI of thedrawings, the horizontal' 4 arm 24 and cup 29 of Fig. V are replaced bya relatively large cup 32 having a bottom 33, preferably, but notnecessarily, having a diameter slightly greater than the radius of thedish 34. The cup 32 provides a means for preventing scattering of piperefuse as do the similar cup elements previously described.

The bottom 33 of the cup 32 is provided adjacentthe periphery thereofvwith an internally threaded boss `or ytubular projection 35 adapted toreceive for rigid 'connection therewith threaded yend 36 of spindle 31which is rotatable in the post 38. Convenient means for mounting post 38in dish' 34 are shown as a nut 33 on threaded exten- 5. ,31.515 thedevice shown 1n sion 4 0 oflpost 38 and bearing against a washer 4Ioi'rthe under surface of the dish.

The. roaming tiool 42 is non-rotatably mounted 1n upright position onthe bottom 33 of the cup 32 fin a' position substantially removed fromthe vertical pivot provided by spindle 31, preferably, but notinecessarily,.centrally of the bottom 33, so that the same simple crank'motion' of the users arm which reams-out a pipe bowlineach form ofthe;device previously described serves t0 perform an -identical function'in themodicaton ofFig.VI. mi'

The .bottom 33 ofthe vcup ,32 is imperforate as illustrated in Fig. VIand hence the cup 32 performs a dual function in that it not. onlyprovides -a rotatable supportingmember forthereaming tool` 42, but. alsofunctions as a Vreceptacle for ashes and dottle-frorni the tobaccopipes. p The spindle 31 .is readily removable from the;post 38 and hencethe cup maybe readily separated from the dish 34and-emptied whendesired.

The dish 34 serves not only as a mounting base for the mechanical partsof the reamer, butalso as a receptacle for pipes,.pipe cleaners and thelike I wi?.

If desired, the bottom'33 of the cup' 32 may be provided with openingssuch as the` openings I0 of Figs. I and II, in which case the dish 34will serve as a receptacle for the ashes `and dottle from the tobaccopipes; as previously described in connection with theforms of the deviceof Figs. ItoIV. v

In the modified form of my pipe reamer shown in Fig. VII of the drawingsthe rotatable supporting member for the reaming tool; -consists of ashallow .cup or pan' 43 having an imperforate bottom 44 andnormallypositioned above and spaced from a relativelyv shallow dish 45.Q'Ihe pan 43, which in this instance serve slalso as a receptacleAforzthe ashes4 and dottle from' the tobacco pipes,

:motion of the usersarm which-reams out a pipe bowl in each'form of thedevice 'previously described serves to perform =an identical function inthe modification of Fig; VII.

.'Ihe'dish 45 serves ynot only asia mounting base for! the mechanicalparts of the reamer, but also as a .rceptacle-fol Pipes, pipe cleanersandfthe like." I r 4 l It? YY1-ay be .eXI'Jlaned thatin allmodcationsriof lthe invention the structure ofthe reamer assembly may beprimarily or wholly of metal in accordance altra-92a with theimplications of the foregoing description anddrawings.V It is, however,possible that all elements of the structure may be made of suitablenon-metallic material suchv as molded plastic, with such change in thedetailed structure of the reamer assembly. as the Vuse Vof suchalternative material will indicate.
